Global plant diversity still hinges on local battles against invasives, study suggests
Scientists at Washington University in St. Louis long suspected that dueling findings about the impact of invasive species on biodiversity reflect the different sizes of study sites. Now field work confims that the impact of invasive species is different at small scales than at large ones. The scientists hope an understanding of this “scale dependence” will help settle arguments that have broken out in the scientific community and discourage recent popular science articles downplaying the damage invasives cause.
Frog fungus hammering biodiversity of communities
Everyone knows that frogs are in trouble. But a recent analysis by Washington University in St. Louis researchers of data on Central American frogs collected by a University of Maryland colleague shows the situation is worse than had been thought.
